Abstract

PURPOSE: To attain an automatic connection to a prescribed device according to the information fed from a telephone line, by discriminating whether the signal is an incoming call of a telephone system or a non-telephone system in a silent section of a short time after detecting an incoming signal to the telephone line and forming a closed circuit.
CONSTITUTION: When an incoming signal of 16Hz is supplied to telephone lines L1 and L2 respectively, this signal is detected by a photocoupler PC and transmitted to a CPU. The CPU actuates a relay Y-1 to form a closed circuit and transmits a prescribed answer word through a sound synthesizing IC1 in case an incoming call of a telephone system is received in a prescribed silent section of a short time. At the same time, the CPU informs through a speaker SP that an incoming call is received and allows talking if an answer is given to the call within a fixed period of time. When a called subscriber is absent, an automatic answering telephone set works to record the message. If the transmission of a carrier signal of a non-telephone system is detected by a terminal device 4 in a silent section, this fact is detected by a transistor TR-1. Then the CPU actuates a relay Y-2 to cut off a telephone TEL circuit and actuate and hold a device 6 by a carrier detecting circuit 5 of the terminal 4.
